CROWBAR.

SPECIFICATION forming part of Letters Patent No. 727,284, dated May 5,1903.

Application filed February 2'7, 1903. Serial No. 145,416. (No model.)

To ztZZ whom, i1; may concern:

Be it known that I, MroHA L F. CAHILL, a citizen of the United States,residing at Lynchburg, in the county of Campbell and State of Virginia,have invented new and useful Improvements in Crowbarsmf which thefollowing is a specification.

My invention relates to new and useful improvements in crowbars; and itsobject is to provide an attachment which is adjust-ably secured theretoand which is soconstructed as to readily engage a timber or othersimilar article placed thereunder and serve as a fulcrum for the bar.

The invention consists in providing a crowbar having a series ofapertures therein, one of which is adapted to receive a pin whichextends through the forked end of a plate which is provided withsharpened lugs or projections at the opposite end.

The invention also consists in the further novel construction andcombination of parts hereinafter more fully described and claimed, andillustrated in the accompanying drawings, showing the preferredform ofmy in;

vention, and in which- Figure 1 is a perspective view of the device.Fig. 2 is a section therethrough. Fig. 3 is an end elevation, and Figs.4 and 5 are detail views showing the mannerin which said bar may beemployed.

Referring to the figures by numerals of reference, 1 is a crowbarpreferably provided with a too 2 at one end thereof and havinga seriesof apertures 3. Any one of these apertures is adapted to receive a boltor pin 4, which extends through ears 5, projecting from a head 6, whichis formed at the upper end of a plate 7. The lower edge of the plate issharpened, as shown at 8, and the ends of said edge have pointed lugs orextensions 9'- sions at the opposite end of theplate. l. 5

bar 1 it can be readily inserted between ties 10 and placed inengagement with a crossbeam 11. By placing the toe 2 in engagement withthe timbers 12 and drawing downward upon the bar in direction of thearrow in Fig. 4 said timbers can be forced upwardly and outwardly. Thesame result can be obtained by reversing the bar, so as to bring the toein engagement with the beam 11 and placing the extensions 9 inengagement with the timbers 12. The bar 1 in-this case can be drawnupward, as indicated by the arrow in Fig. 5. The attachment is extremelysimple and inexpensive and can be the preferred form of my invention;but I do not limit myself thereto, as I am aware that modifications inaybe made therein without departing from. the spirit or sacrificing any ofthe advantages thereof, and I therefore reserve the right to make suchchanges as fairly fall within thescope'ofmy invention.

Having thus described the invention, what is claimed as new is- 1. Thecombination with a bar having apertures therein; of a plate, cars at oneend thereof adapted to receive the bar therebetween, and extensions'atthe opposite end of the plate.

2. The combination with a bar having ap= ertures therein; of a plate,parallel ears at one end thereof adapted to be pivoted to op positesides of the bar, and pointed exten 3. The combinatio'nlwith a barhaving atoe at one end, and a series of'apertu'res; of a plate, a headat one end thereof,,ears projecting from the head extending to oppositesides of the bar,a pivoted bolt withinthe ears and engaging one of theapertures, and extensions at the opposite end of the plate.

4. The combination with a bar having a toe at one end, and a series ofapertures; of a plate, a head at one end thereof, parallel ears I00extending from the head to opposite sides of the plate, parallel earsextending thererd of the bar, a bolt secured to the ears and enfrom, anda pivot-bolt connecting the ears. gaging one of said apertures, asharpened In testimony whereof I affix my signature working edge to theplate, and pointed eX- in presence of two witnesses.
